Abstrak: Dalam industri peleburan aluminium, tekanan panas (heat stress) adalah salah satu bahaya fisik yang paling besar pengaruhnya terhadap keselamatan dan kesehatan pekerja disamping bahaya lainnya. Menurut NIOSH (2016), pekerja yang terpajan panas yang tinggi atau pekerja dengan dengan aktivitas fisik berat kemungkinan akan berisiko terjadinya kecelakaan atau penyakit akibat heat stress. Hasil pengukuran di perusahaan XYZ pada puncak musim panas 2018 menunjukkan bahwa indeks WBGT telah mencapai 37 0 C. Suhu tersebut melebihi nilai ambang batas yang ditetapkan. Di perusahaan peleburan aluminium XYZ, sumber panas luar selain dari proses peleburan, juga berasal dari suhu udara lingkungan, hal ini karena lokasi Perusahaan XYZ berada di wilayah Timur Tengah dengan suhu lingkungan yang tinggi dan kelembaban udara yang tinggi pada saat musim panas. Di wilayah Timur Tengah ada sekitar 6 perusahaan peleburan aluminium yang beroperasi dalam sekala besar, namun sampai saat ini penelitian terkait pengelolaan heat stress masih belum banyak dilakukan. Tujuan penelitian ini adalah untuk mendapatkan gambaran pelaksanaan program pengeloaan Heat stress di Perusahaan XYZ tahun 2019 dibandingkan dengan rekomendasi NIOSH Criteria for a recommended standard: occupational exposure to heat and hot environments - revised criteria 2016. Disain penelitian ini adalah penelitian Mixed Method, yaitu sebagian pengolahan data dinilai secara kualitatif dan sebagian lainnya dinilai secara deskripstif kualitatif dengan metode pengumpulan data berupa data primer dan sekunder. Secara umum, peserta sebagian besar kuisoner menyatakan bahwa perusahaan XYZ telah menerapkan pengelolaan heat stress dengan baik. Dari hasil kuisoner persentase kesesuian sebesar 85,41% dengan rekomendasi NIOSH: Criteria for a recommended standard-ccupational Exposure to Heat and Hot environment- revised 2016 yang sejalan dengan hasil dari hasil wawancara, observasi lapangan yang telah dilakukan. Meskipun demikian masih beberapa hal yang masih perlu dilakukan perbaikan agar risiko tidak terjadi kasus heat stress makin menurun.

Heat stress is one of significant physical hazard in aluminium smelter industry which impact to the health dan safety of the workers. Refer to NIOSH (2016), worker who exposed with high temperature or worker who perform high physical work may be at risk for heat stress or heat related illness. Measurement heat index in XYZ company during peak summer shows that WBGT index reach up to 37 0 C. This Index already reached treshold limit standard. Source of heat in XYZ company generated from process and environment during summer, due to the company location situated in Midle East. It has high ambient temperature and high humidity in peak summer. In the Middle East region, there are six (6) aluminum smelter industry, however heat stress study focusing on heat stress management still not explore intensively. The aim of this study is to review implementation of heat stress arragement in XYZ company 2019 compare with NIOSH Criteria for a recommended standard: occupational exposure to heat and hot environments - revised criteria 2016. The study design is mixed method that using analys qualitatively and descriptive qualitative. The data source collected by primary method dan secondary. In general, as per respondence of quissoinare conclude that XYZ company have implemented heat stress management is good. The quisonaire shows that the percentage of compliance is 85,41% against NIOSH recommendation: Criteria for a recommended standard-ccupational Exposure to Heat and Hot environment- revised 2016. This result aligns with interview and walk trough on the shop floor conducted.

Abstrak: Penelitian ini membahas pelaksanaan Health Risk Assessment di PT X Area Operasi Bagian Utara. Penelitian bertujuan mengkaji data hasil ukur dosis personal selama 1 periode pengukuran tahun 2015 - 2017 dan melakukan penilaian risiko kesehatan dengan metode analisis semi-kuantitatif dengan mengacu Risk Assessment Matrix IPIECA & OGP 2006. Hasil penelitian ini teridentifikasi 9 SEG, namun setelah dikaji secara kuantitatif terdapat SEG yang perlu diklasifikasikan menjadi beberapa sub-group dan health hazard hanya mengacu pada dokumen sekunder sebanyak 10 health hazard. Terdapat keragaman hasil ukur dosis personal dalam 1 SEG menunjukkan salah satu kelemahan pengklasifikasian SEG yang hanya mengacu jabatan pekerjaan saja. Residual Risk Level pada setiap SEG untuk seluruh bahaya gas (Benzene, Toluene, Ethyl Benzene, Xylene) berada pada tingkatan low risk, kecuali untuk H2S yang masuk kategori medium risk. Sementara noise diklasifikasikan low risk pada SEG GS Operator, MWT Operator, Gas Operator, Welder, Company Representative dan noise masuk medium risk pada sebagian SEG Technician shop terutama pada saat pekerjaan metalizing. Risk level bahaya H2S tidak dapat diturunkan menjadi Low mengingat tingkat severity berada pada tingkatan high (4). Penurunan risk level bahaya noise dapat dilakukan dengan konsistensi implementasi HCP dan perlu dilakukan pengukuran efektifitas fungsi earmuff / earplugs untuk mengetahui dosis efektif yang diterima pekerja. Risiko kesehatan pada tingkatan Low Risk, tetap harus dikelola agar level risk tidak meningkat sehingga PT X tetap melanjutkan penerapan existing control dan memastikan pelaksanaan kajian HRA lebih mendalam dengan melakukan observasi / wawancara untuk mengetahui efektifitas implementasi existing control terhadap Potential Risk Level dan Residual Risk Level

This Health Risk Assessment research that was implemented at PT X North Operations Area. The aims of this study was to review the data on personal dose exposure measurement results for 1 measurement period 2015 - 2017 nd conduct a health risk assessment using a semi-quantitative analysis method with reference to the IPIECA & OGP Risk Assessment Matrix Year 2006. The results of this study identified 9 SEGs, but after being studied quantitatively there were SEGs that needed to be classified into several sub-groups and health hazards only referred to secondary documents as many as 10 health hazards. There is a variety of personal dose measurement results in 1 SEG showing one of the weaknesses in the classification of SEG which only refers to job title. The Residual Risk Level in each SEG for all gas hazards (Benzene, Toluene, Ethyl Benzene, Xylene) is at a low risk level, except for H2S which is in the medium risk category. Meanwhile, noise is classified as low risk in SEG GS Operators, MWT Operators, Gas Operators, Welder, Company Representatives and noise is a medium risk in several SEG Technician shops, especially during metalizing work. The H2S risk level cannot be lowered to low considering that the severity level is at a high level (4). Reducing the risk level of noise hazards can be implemented by consistent implementation of HCP and it is necessary to measure the effectiveness of the earmuff / earplugs function to determine the effective dose received by workers. Health risks at the Low Risk level must still be managed so that the risk level does not increase so that PT X continues to implement existing controls and ensure the implementation a comprehensive HRA study by conducting observations / interviews to determine the effectiveness of implementing existing controls on the Potential Risk Level and Residual Risk Level
